  • ffmpeg progress percentage in php

    9 avril 2018, par Mr.ZZ

    ffmpeg.php

    $sCmd = "ffmpeg -i ".$image." -i ".$music." video.avi 1> progress.txt";
    
$proc = popen($sCmd." 2>&1", "r");

    progress.php

    $content = @file_get_contents('progress.txt');
    
if($content){
    
    preg_match("/Duration: (.*?), start:/", $content, $matches);
    
    $rawDuration = $matches[1];
    
    $ar = array_reverse(explode(":", $rawDuration));
    
    $duration = floatval($ar[0]);
    
    if (!empty($ar[1])) $duration += intval($ar[1]) * 60;
    
    if (!empty($ar[2])) $duration += intval($ar[2]) * 60 * 60;
    
    preg_match_all("/time=(.*?) bitrate/", $content, $matches);
    
    $rawTime = array_pop($matches);
    
    if (is_array($rawTime)){$rawTime = array_pop($rawTime);}
    
    $ar = array_reverse(explode(":", $rawTime));
    
    $time = floatval($ar[0]);
    
    if (!empty($ar[1])) $time += intval($ar[1]) * 60;
    
    if (!empty($ar[2])) $time += intval($ar[2]) * 60 * 60;
    
    $progress = round(($time/$duration) * 100);
    
    echo $progress;
    
}

    progress.php final output was always 100, so it was easy with jquery to hide progress and show download button.

    BUT after changing ffmpeg.php with this command :

    $sCmd = "ffmpeg -loop 1 -r 1 -i ".$image." -i ".$music." -c:a copy -shortest video.avi 1> progress.txt";
    
$proc = popen($sCmd." 2>&1", "r");

    progress.php output is different numbers above 100(thousands) and jquery can’t figure out ffmpeg process finished or not.

    How to get 100 when ffmpeg finishs working ? I think i need some changes in progress.php because final result in progress.txt is longer than before.

  • convert video to audio using ffmpeg

    5 mai 2024, par shakti goyal

    I'm trying to convert a video to mp3 using ffmpeg library but ffmpeg command is not working, it is returning the code 1

    


    Video conversion to MP3 failed with return code : 1

    


    try {
  final session = await FFmpegKit.execute('-i $videoFilePath -vn -ar 44100 -ac 2 -b:a 192k -f mp3 $audioFilePath');

  final returnCode = await session.getReturnCode();

  if (ReturnCode.isSuccess(returnCode)) {
    print('Video conversion to MP3 successful!');
  } else {
    print('Video conversion to MP3 failed with return code: $returnCode');
  }
} catch (e) {
  print('Error occurred during video conversion: $e');
}


    


    $videoFilePath - /Users/shaktigoyal/Library/Developer/CoreSimulator/Devices/9D514AC1-E245-4360-B876-745B9527B844/data/Containers/Data/Application/091D48E6-3AE4-4867-B3B2-2034854D27CE/tmp/image_picker_3DA6CDD3-C2F9-4313-98A1-40A7B0AED652-1298-00001B041C9F94E4trim.59BC5143-1EBA-4BB0-955C-EA1942FA56E3.MOV

  • ffmpeg : combine two or three audios into one by lowering the volume of the other

    15 juin 2016, par somya bhargava

    Want to combine some audio files eg :

    1) one long audio file which will act as a background audio
    2) some audio files which will be replaced at specific intervals
    like at 10 sec of the first one

    So final output required is
    audio-1 60 sec
    audio-2 starting from 10 sec to 20 sec with audio-1 at 0.1 volume
